Answer:

To solve the equation 85w^2=160 for w, we need to isolate w on one side of the equation.

First, divide both sides by 85:

85w^2/85 = 160/85

Simplifying, we get:

w^2 = 1.88235294118

To solve for w, we need to take the square root of both sides:

sqrt(w^2) = sqrt(1.88235294118)

Since w is a positive length, we can drop the negative square root, so we have:

w = 1.3725...

Rounding to the nearest hundredth, we get:

w ≈ 1.37 ft

Therefore, the width of the backdrop is approximately 1.37 feet.

Answer:

x  = 2y + 5    (1)

x^2 + y^2  = 5  (2)

Step-by-step explanation:

Sub (1) into (2) to find the y intersection of these functions

(2y + 5)^2  + y^2  =  5      simplify

4y^2 + 20 y + 25 + y^2  = 5

5y^2 + 20y +20  = 0      divide through by 5

y^2 + 4y + 4  =  0      factor

(y + 2)^2  = 0        take the square root of both sides

y + 2   = 0

y  = -2

And x  =    2(-2) + 5   =  1

So....(1, -2)  is the tangent point  because it  is the only point that makes both equations true

1 = 2(-2) + 5   is true      and

(1)^2  + (-2)^2  = 5     is also true

Let's represent the apple as = X

Let's represent the pear as = y

That is ;

4x + 3 y = 4.10. ---> equation 1

5x +8y = 6.40 ----> equation 2

Make X the subject of formula in equation 1

4x = 4.1-3y

X = (4.1-3y)/4

substitute X = (4.1-3y)/4 into equation 2.

5[(4.1-3y)/4] + 8y = 6.40

20.5-15y+8y = 6.40×4

20.5 - 7y = 25.6

-7y = 5.1

y = 5.1/7

y = 0.73

Substitute y = 0.73 into equation 1;

4x + 3(0.73) = 4.10.

4x + 2.19 = 4.10

4x = 4.20-2.19

Answer:

A. 1/3

Step-by-step explanation:

The probability of drawing a blue marble on the first draw is 2/4, or 1/2, since there are two blue marbles out of four total marbles. After one blue marble has been drawn and not replaced, there are now three marbles left in the bag, one blue and two green. Therefore, the probability of drawing a green marble on the second draw is 2/3.

To find the probability of both events happening, we multiply the probabilities:

P(blue, then green) = P(blue) * P(green after blue)

P(blue, then green) = 1/2 * 2/3

P(blue, then green) = 1/3

Therefore, the probability of drawing a blue marble followed by a green marble, without replacing the first marble before drawing the second marble, is 1/3. Answer: 1/3.

The approximate amount of paint needed =  438.03 cm²

The correct answer is an option (D)

We know that the formula for the surface area of the cylinder is :

A = (2 × π × r × h) + (2 × π × r²)

Here, the diameter of the can is 9 sm

So, the radius of the can would be,

r = d/2

r = 9/2

r = 4.5 cm

And the height of the can is h = 11 cm

Since the can is cylindrical, we use above formula of surface area of the cylinder to find the amount of paint needed.

Using above formula,

A = (2 × π × r × h) + (2 × π × r²)

A = (2 × π × (4.5) × (11)) + (2 × π × (4.5)²)

A = 311.02 + 127.01

A = 438.03 cm²

Complete Question:

What is the surface area of the triangular prism shown?

32 square centimeters

184 square centimeters

1,560 square centimeters

Answer:

Step-by-step explanation:

To solve for the angles, you can use the fact that the sum of the angles in a triangle is 180 degrees.

So, you can set up an equation:

43 + 3x + (5x-5) = 180

Simplifying, you get:

8x + 38 = 180

Subtracting 38 from both sides:

8x = 142

Dividing both sides by 8:

x = 17.75

Now that you know x, you can plug it into the expressions for the other two angles to find their measures:

First angle = 3x = 3(17.75) = 53.25

Third angle = 5x - 5 = 5(17.75) - 5 = 83.75

Therefore, the three angles are 43 degrees, 53.25 degrees, and 83.75 degrees.

Now, we have to find the greatest common factor of these two expressions. Firstly, we will find the factors of these two expressions and then the greatest among them.

16[tex]y^{8} x^{2} u^{3}[/tex] = 8[tex]y^{5} x^{2}[/tex] × [tex]2y^{3} u^{3}[/tex]

8[tex]y^{5} x^{4}[/tex] =  8[tex]y^{5} x^{2}[/tex] × [tex]x^{2}[/tex]

So, the common greatest factor between both of these is  8[tex]y^{5} x^{2}[/tex]. Hence, the answer is  8[tex]y^{5} x^{2}[/tex].

sin 2Θ = 720/1681

cos 2Θ = 1521/1681

tan 2Θ = 720/1521

We have,

Since sin Θ = -9/41 and Θ lies in quadrant III, we can use the Pythagorean identity to find the value of cos Θ:

cos²Θ = 1 - sin²Θ

cos²Θ = 1 - (-9/41)²

cos²Θ = 1 - 81/1681

cos²Θ = 1600/1681

We know that the number of insects at the start of the year (n+1) is P+1, where [tex]P_n+1 = kP_n[/tex]

So, we can write:

[tex]P1 = kP_0\\P_2 = kP_1 = k(kP_0) = k^2 P_0\\P_3 = kP_2 = k(k^2 P_0) = k^3 P_0\\P_4 = kP_3 = k(k^3 P_0) = k^4 P_0\\[/tex]

[tex]Pn = k^n P_0[/tex]

To find out how many years it takes for the number of insects in the population to double, we need to find the value of n such that Pn = 2P0.

So, we have:

[tex]2P_0 = k^n P_0[/tex]

Dividing both sides by P_0, we get:

[tex]2 = k^n[/tex]

Taking the natural logarithm of both sides, we get:

[tex]ln 2 = n ln k\\n = ln 2 / ln k[/tex]

Substituting the value of k as 1.13, we get:

n = ln 2 / ln 1.13
